This change in weather fortunes comes about thanks to a blocking area of high pressure building across Greenland with cold Arctic air emptying out across the UK and bitter northerly winds developing.

At the end of this weekend and into next week there are some convincing signals of a northerly wind developing.

In September, temperatures continued to be warmer than expected as the sub-tropical jet stream's more northerly position allowed a warmer southerly flow of air over Japan.

During La Niña, unusually cold temperatures in the equatorial Pacific Ocean typically send winter storms on more northerly tracks, leaving the southern U.S. warmer and drier.

Across the north-west of Scotland conditions will improve too with drier, less moist air filtering down on a cold northerly wind.
